WVhile the grooved presser may, if desired,

By the lateral adjustment of the jaw h, therefore, the

- width of the passage for the toothed strip may be regulated with thegreatest nicety to accord with the thickness of the toothed strip whichis being wound upon the cylinder, so as to prevent the passage to thepresser of any portion of said strip which is of such undue thickness aswouldtend to cause injury to thecylinder or presser in an attempt topress it into the groove of the cylinder. Such thickened portion of thestrip will be caught and retained by the guide-jaws h h and the toothedstrip will be brokenythu's giving the attendant an opportunity to removethe thickened portion of the strip before resuming the windingoperation, the firmness with which the toothed strip is pressed into thegroove ofthe cylinder preventing the unwinding of the broken or free endof the strip before the final calking of the cylinder.

The guide G may be adjusted laterally by swinging it on the-tool-post,so as to bring the passage for the toothed strip directly in line withthe groove in which said strip is being wound.

It will of course be understood that as the cylinder A is rotated in thelathe the tool-post B is traversed longitudinally at a rate of speeddependent upon the pitch of the spiral groove cut in said cylinder. i Weclaim as our invention 1. The within-described tool for effecting theapplication of a toothed strip to a grooved cylinder, said toolconsisting of a presser having a groove for the reception of the toothedstrip, and opposite pressing-flanges constructed to bear upon the sidesof the strip below the tips of the teeth of the same, all substantiallyas specified.

2. The within-described tool for applying toothed strips to groovedcylinders, said tool consisting of a rotating presser having flanges forbearing upon the opposite sides of the strip, all substantially asspecified.

3. The within-described tool for applying toothed strips to groovedcylinders, said tool consisting of a rotating presser having a groovewith flaring sides adapted to bear upon the flaring sides of the strip,all substantially as specified.

4. The within-described pressing-tool, consisting of a bar, arotatingpresser, and sleeves forming bearings for the journals of said presser,said' sleeves being adjustable in respect to the bar, all substantiallyas specified.

5. The within-described pressing-tool, consisting'of a bar having aforked end, a pair of 'pressing-disks,and laterally-adj ustable sleevescarried by the forked end of the bar and forni ing bearings for thespindles of said disks, all substantially as specified.

6. The within-described guide for directing a toothed strip to a groovedcylinder, on which it is to be wound, said guide consisting of a pair ofrigid jaws, providing between them a passage which approximates closelyto the normal thickness of the strip, all substantially as specified.

7. Thewithin-describedguideforthetoothed strip, said guide consisting ofa fixed jaw and a movable jaw, forming between them a passage for saidstrip, all substantially as specified.

- 8. The combination of the rotary presser for bearing upon the sides ofa toothed strip and forcing the same into the groove of the cylinder,with a pair of jaws between which the strip passes before reaching thepresser, all substantially as specified 9. The combinationof thelathe-post, the presser'bar carried thereby, and the guidebar secured tothe post and adjustable circumferentially thereon, all substantially asspecified. i

In testimony whereof we havesigned our names to this specification inthe presence of two subscribing witnesses.
